EQUIPMENT FOR LASER RADIATION GUIDANCE Russian patent published in 1995 - IPC

FIELD: quantum electronics. SUBSTANCE: equipment for laser radiation guidance includes supporting rotary device 1, first telescopic system 5, first laser 7, first Fourier lens 9, first spatial-time light modulator 10 and matrix photodetector 12 optically coupled as well as optical quantum amplifier 16, second laser 25, coordinate determination unit 14, unit 15 generating control signals. Equipment is inserted with second telescopic system 6, unit 18 of reversal of wave front, second Fourier lens 19, second spatial-time light modulator 20 lens 3 and photodetector 22 coupled optically as well as with laser 27, two-coordinate scanner 29 of laser radiation. Optical output of second telescopic system 6 is connected to first optical input of unit 18 of reversal of wave front via optical quantum amplifier 16. Optical output of second spatial-time light modulator 20 is coupled to second optical input of unit 18 of reversal of wave front via semi-transparent mirror 35, second Fourier lens 19 and reflection mirror 33. Output of second laser 25 is optically coupled to input of second spatial-time light modulator 20 and to first optical output of unit 18 of reversal of wave front, input of photodetector 22 is connected to output of unit 18 reversal of wave front. EFFECT: increased precision of guidance of laser beam on object. 1 dwg
